cannot redistribute partition throughput on cosmosdb with >50 partitions

[IanBrown-OAG]

Describe the bug

using https://learn.microsoft.com/en-us/cli/azure/cosmosdb/sql/container?view=azure-cli-latest#az-cosmosdb-sql-container-redistribute-partition-throughput which admittedly is in preview, to even out the RU distribution, it fails with an error

Related command

az cosmosdb sql container redistribute-partition-throughput --resource-group $resourceGroupName --account-name $accountName --database-name $dbName --name $containerName --evenly-distribute

Errors

az : ERROR: (BadRequest) Message: {"code":"BadRequest","message":"Message: {"Errors":["Max allowed partition throughput reads per request is currently 50."]}\r\n

Issue script & Debug output

cosmos_error.txt
too large to insert, attached

Expected behavior

I expect it to redistribute the RUs across the partitions.
